If you file your emails into folders in your email program you're wasting your time, according to a study by IBM Research. The 345-user study found that people who used the search function in their email program could find relevant emails as easily as those who had categorised each email into folders. Finding emails by searches took on average 17 seconds, versus 58 seconds finding the emails by folder. The likelihood of success - that is, finding the intended email - was no greater when it had been filed in a folder. "People who create complex folders indeed rely on these for retrieval, but these preparatory behaviours are inefficient and do not improve retrieval success. In contrast, both search and threading promote more effective finding," the study said.
